摘要 An interesting metal-organic framework (MOF) PFC-31 was synthesized by a simple solvothermal reaction. X-ray crystallography reveals that PFC-31 crystallizes in monoclinic system, space group P21/c with a = 6.8410(17), b = 20.123(5), c = 7.689(2) Å, β = 104.239(7)°, V = 1026.0(5) Å3, Z = 2, C16H22CuN4O8S2, Mr = 526.03, μ = 1.322 mm–1, Dc = 1.703 g/cm3, F(000) = 542, GOOF = 1.214, R = 0.0975 and wR = 0.2324. According to X-ray analysis, PFC-31 shows one-dimensional chain constructed by Cu(II) centers coordinating with two pyridine groups, two sulfonate groups and two DMF molecules. Owing to the orderly functionalized sulfonate group and Lewis metal sites, PFC-31 exhibits good catalytic capability for CO2 cycloaddition of epoxide under normal pressure and temperature.

Abstract：An interesting metal-organic framework (MOF) PFC-31 was synthesized by a simple solvothermal reaction. X-ray crystallography reveals that PFC-31 crystallizes in monoclinic system, space group P21/c with a = 6.8410(17), b = 20.123(5), c = 7.689(2) Å, β = 104.239(7)°, V = 1026.0(5) Å3, Z = 2, C16H22CuN4O8S2, Mr = 526.03, μ = 1.322 mm–1, Dc = 1.703 g/cm3, F(000) = 542, GOOF = 1.214, R = 0.0975 and wR = 0.2324. According to X-ray analysis, PFC-31 shows one-dimensional chain constructed by Cu(II) centers coordinating with two pyridine groups, two sulfonate groups and two DMF molecules. Owing to the orderly functionalized sulfonate group and Lewis metal sites, PFC-31 exhibits good catalytic capability for CO2 cycloaddition of epoxide under normal pressure and temperature.
